Hi,
thanks T.Prince,
Your saying:
"I'll just mention that we are well into the era of 3 levels of
programming parallelization: vectorization, threaded parallel (e.g.
OpenMP), and process parallel (e.g. MPI)." is a really great new
learning for me. Now I can perceive better.

Suppose we run a parallel MPI code with 64 processes on a cluster, say

means all processes has the same workload.
